Have you met Kat Colorado yet? If not, run, don't walk, to your nearest bookstore and get aquainted.
Kat is a P.I located in Sacramento, CA. Surrounded by a variety of colorful characters. She works each case depending on her sharp wit and has a strong dedication to her client (well, ok...most of the time.)

When is the next Kat book coming out?

I wish I knew. There are a few rumors out there. The two that I keep hearing are (1) She lost her contract with Putnam and is looking for a new publisher and (2) She's quit writing due to family obligations. I don't know whether either one is true, she's the only one who can say for sure. I just hope that she either gets a new publisher or gets her family obligations taken care of soon. :)
I recently heard a new rumor. Her latest book is ready to go, but her publisher wanted to go straight to paperback and she refused.
